Thanks for the reply Kirk. I like your idea but I do not think our IT department will go for it. They are already very unhappy that we are creating an extension in addition to a custom toolbar so I seriously doubt they are going to let us run a service in the background on their Citrix server. Whatever solution I end up using, it has to be contained within my extension or .dll file. Ideally, the logic my boss wants to see is: Track anything the user adds from the Add Data button that is on an Enterprise server (not local data), write this to an Access or Oracle table and keep a running total of how many times each particular data set is loaded so we can detect the most popular ones for inclusion on the forms. I thought about adding a timer so that I can fire code to see what is in the TOC say every 5 minutes but I strongly suspect this would adversely affect performance as this was the case once before when I tried using timers through Citrix. ...

James, Thanks for the reply. Unfortunately, it is not working correctly. The code in the customization filter detects when the Add Data button is pressed and then immediately executes your line of code before the user even adds anything to the TOC.     if (pCommandItem.Name.ToString() == "File_AddData")     { MessageBox.Show("Add Command Executed"); IApplication pApplication = ClsHelper.GetArcGISApplication(); IMxDocument pMxDocument = (IMxDocument)pApplication.Document; IMap pMap = pMxDocument.FocusMap; IFeatureLayer pFeatureLayer = pMap.get_Layer(0) as IFeatureLayer; MessageBox.Show("Layer name: " + pFeatureLayer.FeatureClass.AliasName);     } ...

Thanks Ken, I'll try to make sense of it all and give it a try. I'll let you know what happens. Carlos ... View more

Ken, Thanks for the reply! Being that this is my first attempt at writing an extension, I am trying to follow an ESRI example as closely as possible because I still don't understand everything that is going on in the code. In their example, they initialize m_extensionState at the top so I left it there. I tried to not setting it to a value at the start (private esriExtensionState m_extensionState) and that caused another problem. If I didn't set m_extensionState to disabled at the start, the else if disabled code would run in the state property regardless if the extension was checked on or off in the extension manager. Could you send me your code so I can see where you are setting m_extensionState? Thanks, Carlos In the extension I developed, I used the same ESRI example as you did. One thing that is different between our code is when you initialize the variable m_extensionState. When you initialize it, you're also setting it to disabled. In my code, the variable gets set to either disabled or enabled in the State Property. ... View more

Kirk, I solved it! The problem was with this line of code at the top of the extension: private esriExtensionState m_enableState; should be: private esriExtensionState m_enableState = esriExtensionState.esriESDisabled; I guess I must have copied/pasted wrong when I copied the example. Thanks again for your help! It is always greatly appreciated! Carlos ... View more

Thanks Kirk, I will give it a try. In your code, what code should method AMethodThatMightThrowAnException contain? ... View more

Kirk, Thanks for the reply. You are correct, as far as I can tel, IApplicationStatus.Initialized is indeed false in the startup method. How do I correct this? I am using the AcmeExt (Applying user interface customizations at startup) ESRI example along with the default code that comes with the ApplicationExtension template and I must admit I don't understand some of it but figured if it is in their example, I should not mess with it. Last night as a test, I installed the ESRI example, put message boxes in the same locations as in my code and when I started ArcMap, I got the same result, message box displaying in the disabled code eventhough I had not yet turned on the extension. I'm beginning to think that the problem might be with the example. Anyhow, below is my entire extension as it currently stands. Can you please take a look at it and see if you can tell what the problem is and how I can fix it? I will look at JIT extension and see if that might work better for me. Hopefully I can find some examples of those. Thanks a lot!

Thanks Kirk, I think I understand what you are saying. I will give it a try. Do you have an example I can follow? Thanks, Carlos ... View more

Hi Ken, Got it working with your code. Thanks a bunch! Here's the code in C# in case in helps someone else.         public override bool Enabled         {             get             {                 UID pUID = new UIDClass();                 pUID.Value = "RegGSS.Extension";                 IExtensionConfig pExtension = m_application.FindExtensionByCLSID(pUID) as IExtensionConfig;                 if (pExtension == null)                     return false;                 if (pExtension.State == esriExtensionState.esriESEnabled)                     return true;                 else                     return false;             }         } ...

Ken, Thanks for the reply. I think I understand what you are saying and I will give it try. Do you have a code example where you are using the previous code you sent me so I can see how to set it up properly? Thanks again for your help. Carlos As you state, OnCreate is only fired when the command is created, whereas Enabled is fired continuously (which is also why you shouldn't have any extensive code in that subroutine). This will react to any changes in the environment, like enabling the extension. ... View more

Ken, Thanks for the reply. Unless I am not understanding correctly, your code is doing the same thing mine is doing, disabling the commands on the toolbar if the extension is turned off. My problem is if the user turns on the toolbar first and then the extension, the commands on the toolbar stay disabled because the code to enable/disable the command in on the "on create" for the command and since the toolbar is already on, the "on create" code does not excute again. I was thinking I could refresh the command somehow but can't figure out how to do that. Thanks again for your help! Carlos ... View more
